Pyridoxine storage

[Tom Ashton]

I want to use Pyridoxine as an internal standard in LC.
I have dry powder but I want to know if it is possible to make an aqueous solution of the desired molarity and store it this way.
If so at what temp must I store it?
Any advice would be much appreciated.

hello,tom

in my experience,solutions of piridoxina in suitable diluente like (water:acetonitrile: acetcic acid) ,94:5:1,can to use them well,for two months.

it works to me.
